What are the 2 factors that multiply 15000 and adds up to 5
s2008m [1.1K]
Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so

xy=15000
x+y=5


x+y=5
y=5-x

x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

x^2-5x+15000
a=1
b=-5
c=15000
x=\frac{-(-5)+/- \sqrt{(5)^{2}-4(1)(15000)} }{2(1)}
x=\frac{5+/- \sqrt{25-60000} }{2}
x=\frac{5+/- \sqrt{-59975} }{2}
x=\frac{5+/- 5i\sqrt{2399} }{2}
so the numbers are
\frac{5+ 5i\sqrt{2399} }{2} and \frac{5- 5i\sqrt{2399} }{2}

Tcecarenko [31]

The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}  is the expression \frac{2}{k+2}

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the expression:

(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} \\\\This\ can\ be\ simplified\ to:\\\\(\frac{2(2k+1)(k-2)}{(k+2)(k-2)(2k+1)}) \\\\=\frac{2}{k+2}

The product of the expression (\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} is the expression \frac{2}{k+2}
